Postecoglou has stuck with the attacking formation since using it in a World Cup qualifier against Iraq in Tehran in March, though local media pundits have questioned whether Australia have the players to pull it off successfully.

Degenek added: "They won't underestimate us - they will see from our second half against Germany that we are a team that plays a lot of good football".

With three matches in seven days and substantial travel between venues, Postecoglou said "it doesn't make sense to keep going in with the same XI" as he plots a route to the semi-finals that, in all likelihood, will require wins over both the African Champions and Chile in Moscow three days later.

- Cameroon managed just one shot on target against Chile, fewer than every other side in the competition and four fewer than Australia.

"[The players are] loyal participants", Postecoglou said.

The national team coach has promised "at least" two changes for Thursday night's (Friday 1am AEST) clash with Cameroon. It's something we've been building up towards for the last three years with Ange in charge. If that's his opinion I don't know what he's watching but from our perspective we certainly know how we want to play our football.

"I don't think (the Cameroon match) is going to be any easier than the first one or the third one". So you've got two contrasting opinions.

"I'm absolutely over the moon that there's debate", he told a pre-match news conference. "It's true that we lacked a little bit of a threat on the Chile goal but apart from that, I'm happy". But in response Postecoglou gave Broos' comments short drfit.

The Indomitable Lions seemed destined for a famous draw against Chile until the 82nd minute when Bayern Munich midfielder Arturo Vidal opened the scoring Eduardo Vargas, whose blaze was ruled out by the video assistant in the first half, added a second in additional time after another video review.

This will need to improve if they are to have a chance of beating Australia in this game.

"What I have seen is there has been a development, a positive development", he said through a translator.

Hugo Broos' team will need to show more endeavour and endurance against an Australian team which managed to impress in patches during their 2-3 loss to world champions Germany on Monday.
